PR-4 batch 4: import-from-definer in gunbc site/ci cluster

[briansrls]

Summary

Namespace flip Track B — PR-4 import-from-definer, bounded batch 4 (gunbc site/ci cluster).

Repoints 13 import groups across 8 files so each import M { X } names the defining module, not a re-export surface.

Area	Files	Repoint pattern
deploy access	ci_deploy_access_emit.dag	grounded_posix_principal_name: gunbc.ci_deploy_access → gunbc.fleet_posix_accounts
host effects	host_effect_plan.dag	FreeMonoid: v2.std.algebra → std.algebra
site	accent_study.dag, moodboard.dag	gunbc.site.tokens / register_principles → gunbc.design.{theme,material,principles}
claim tests	site_register_witness_test.dag, wcag_contrast_witness_test.dag	gunbc.site.{tokens,interaction} → gunbc.design.{theme,material,interaction}
CI tools	ci_gates.dag, floor_effect_gate_witness.dag	EmitHostGate/Gate: gunbc.ci_spec → gunbc.ci_gate

No regen input touched (dag/ only, no src/v1/** changes).

Remaining corpus

Census after this batch: 31 name-sites / 26 groups — v2 language emit (#7142), v2 lens parallelism, v2 std/misc.

Test plan

• regen_stage0 --verify → regen_divergence_count=0 (no-op on this diff)
• CI green

Verified review 42043 (claude/claude-opus-4-7 APPROVE) against HEAD dd4ebbc: import-only repointing — grounded_posix_principal_name from gunbc.fleet_posix_accounts, FreeMonoid from std.algebra, EmitHostGate/Gate from gunbc.ci_gate, site symbols split to gunbc.design.{theme,material,principles,interaction}. Census confirms the gunbc site/ci cluster is clear. No code changes warranted.

Review 42047 is correct — fixed in latest push.

ci_gates.dag repoint moved EmitHostGate/Gate to gunbc.ci_gate but accidentally dropped CheapClaimPoolGate and LayeringImportsGate from scope while run_spec_gate still matches on them. Added both to import gunbc.ci_gate { … } (their definer, per ci_gate.dag).

Addressed review 42057 in ff729fd3:

1. floor_effect_gate_witness.dag — CheapClaimPoolGate / LayeringImportsGate now import from gunbc.ci_gate (same as ci_gates.dag).
2. site_register_witness_test.dag — Enter, Receipt, HashElement moved to gunbc.design.interaction; dropped the gunbc.site.interaction façade import.
3. accent_study.dag — register_thesis from gunbc.design.principles (matches moodboard.dag).
